Title: Improvements in apparatus for conveying cigarettes
IPC: A24C5/33
Filed: 1960-06-08
Abstract: 955,596. Conveying filter-tip cigarettes. G. F. PEMBROKE, J. G. E. HILLMAN, and MOLINS MACHINE CO. Ltd. June 7, 1961 [June 8, 1960], No. 20094/60. Heading A2C. One of two rows of filter-tip cigarettes, while being conveyed from the cutting device of a filter-tip cigarette-making machine, is first slightly displaced axially by a wedge and then further displaced axially by an air blast directed against the ends of the cigarettes to separate the rows prior to the collecting tray filling operation. Assemblages consisting of two pieces of cigarette rod with a double length filter tip between, secured together by a wrapping strip, are fed by a fluted drum 1 (Fig. 1) to a cutting disc 4, which bisects each one to form two filter-tip cigarettes. The separated cigarettes roll down a stripper ramp 6, under a light spring plate 7, passing either side of a wedge 5 (Fig. 4), to a roller 8 on which the stub parts only of the cigarettes are subjected to rolling pressure under an arcuate plate 9. The cigarettes then fall into the flutes of a drum 11, passing either side of a plate 10 (Figs. 1 and 3) through which an air blast is directed from an aperture 19 against the ends of the near side row of cigarettes moving them axially to an extent determined by a stop disc 14 rotating with the drum 11. The near side row then roll down a stripper plate 12 to a conveyer 13 leading to a tray filling device. The far row is carried by a chain conveyer 15 to a rotatable suction head 16, which siezes and turns each cigarette through 180 degrees, as described in Specification 900,387, before depositing them on to another conveyer. In one modification (Fig. 5, not shown), the assemblages are conveyed in a controlled manner by a chain having vertical abutments, against which the cigarettes rest, which carries them through the cutting disc 4. The cut cigarettes are temporarily released from the chain to pass through a rolling device. On returning to the chain, the rows are axially separated, and one rows is passed to the stripper plate 12 and the other to the suction head 16. In another modification (Fig. 6, not shown), the cigarettes are stripped from the drum 1 by lugs on a plurality of axially spaced conveyer discs. The cigarettes, while on the conveyer, and after being initially controlled by a light spring, are raised slightly by a drum placed between the discs and the tips of the cigarettes are rolled between this drum and an arcuate plate. The cigarettes then return to the conveyer to be separated by an air blast, and one row is turned through 180 degrees as before.

Title: Improvements in or relating to electric discharge devices
IPC: H01J61/12
Filed: 1936-07-21
Abstract: 476,066. Discharge apparatus. GENERAL ELECTRIC CO., Ltd. (Patent-Treuhand-Ges. fiir Electrische Gl³hlampen) July 21, 1936, No. 20177. Drawings to Specification. [Class 39 (i)] The characteristic of the positive column of a discharge device is rendered positive by the promotion of electrophoresis. Electrophoresis may be promoted by reducing thermal diffusion, e.g. by the use of a tube of small diameter, and by making large the difference in the ionization potentials of the component fillings. When the tube is energized by an alternating potential, the alternating discharge current should be asymmetrical; this may be obtained by providing the tube with one cold electrode and with one thermionic electrode, or with two thermionic electrodes which have different electron emission, or with two cold electrodes and by earthing a suitable point on the tube which is supplied from a secondary winding which is earthed. A metal which is completely evaporated during operation may be provided, and is preferably located at the cathode end. A lamp, the dimensions of which are stated in the specification, may have a filling of neon at 4 mms. and mercury at atmospheric pressure, and red and blue light is emitted from different parts of the tube. In another form, the filling may consist of argon and sodium. Specification 424,322 is referred to.

Abstract: 1,260,940. Knitting-machines. MECMOR S.p.A. 21 April, 1969 [27 April, 1968], No. 20292/69. Heading D1C. A yarn changing device comprises an indexable drum 5 carrying a series of guides 8, the index steps being selectively controlled by a series of stops 26 movable relative to the drum. The guides are slidable in slots 7 cut in the periphery of the drum which is rotatable anti-clockwise by a spring. A series of steps 18 fixed to the drum and engageable by a spring loaded plunger 20 permits each guide to be located under a plunger 10. When a yarn is to be changed the plunger is raised to withdraw the active guide and a selected stop 26 projected into the path of the steps. If the next active guide is clockwise of that previously active the slope 27 of the stop engages and raises the plunger 20. The drum turns in steps till the corner of the stop engages the appropriate step where the plunger remains. Plunger 10 is lowered to activate the new guide. If the next active guide is anticlockwise of the last, the corner of the selected stop engages the appropriate step. As relative movement between the two occurs the drum is indexed and plunger 20 drops to the required step. Yarn is clamped at the base of the guides by a resilient strip (30, Figs. 6, 7 not shown) released when the guide is active by a plunger (32).

Title: Hearing aid
IPC: H04R25/04
Filed: 1973-04-30
Abstract: 1428466 Hearing aid circuits; automatic gain control RION KK 30 April 1973 [16 Oct 1972] 20483/73 Headings H4J and H4R In a hearing aid, a portion of the frequency spectrum of the output signal from a microphone is used to derive a control signal and this control signal is used to control the frequency characteristic of the output signal of the hearing aid. In one embodiment (Fig. 2) the hearing aid includes a control signal microphone 24 and a conversation microphone 36. The output of microphone 24, after amplification, is applied to a filter 28 which rejects three portions of the frequency spectrum required for conversation i.e. of range about 300 to 3000 Hz. The signal components with frequencies below 300 Hz and above 3000 Hz are, after amplification, applied to a rectifier circuit 34 which derives a positive control voltage. This is applied to a lower band control circuit 38 and a higher band control circuit 40. A volume control 30 sets the control threshold level. The arrangement is such that if the ambient noise level outside the range 300 to 3000 Hz received by microphone 24 is above a certain level, the upper and lower frequency ranges of the signal received by microphone 36 are attenuated by the control circuits 38, 40 and the sounds heard through an earphone 48 are concentrated in the frequency band required for converstion. Increase of the ambient noise level results in increased attenuation by circuits 38, 40. An alternative arrangement (Fig. 5) uses a single microphone 36<SP>1</SP> which functions as both a control microphone and a conversation microphone and is connected to the control generator circuit 22 and also to a lower band control circuit 38<SP>1</SP> including a F.E.T. Q 4 . A rectifier circuit 34 provides a positive control voltage to higher band control circuit 40 while a rectifier circuit 35 provides a negative control voltage to the lower band control circuit 38<SP>1</SP>.
